Struct perf_event_data::RecordMetadata

pub struct RecordMetadata { /* private fields */ }

Extra record data emitted by the kernel that is common to all records.

Implementations

impl RecordMetadata

pub fn ty(&self) -> u32

The type of this record, as emitted by the kernel.

pub fn misc(&self) -> u16

Miscellaneous flags set by the kernel.

pub fn sample_id(&self) -> &SampleId

If sample_id_all was set when configuring the record then this will contain a subset of the fields configured to be sampled.

Note that, even if sample_id_all is set, MMAP and SAMPLE records will always have an empty SampleId. If you want the SampleId fields to be set then configure the kernel to generate MMAP2 records instead.
